AMD Radeon RX Vega 64 vs NVIDIA GeForce RTX 4070 Ti Comparison

The AMD Radeon RX Vega 64 and NVIDIA GeForce RTX 4070 Ti represent two distinct eras of GPU design, separated by over five years of architectural evolution. The data shows a decisive performance gap, with the RTX 4070 Ti winning all three head-to-head benchmarks by substantial margins. However, the RX Vega 64’s legacy as a high-bandwidth, large-die flagship remains relevant for understanding how far GPU technology has progressed.

Head-to-Head Benchmarks

The benchmark results are unambiguous: the NVIDIA GeForce RTX 4070 Ti dominates every shared test. In 3DMark Steel Nomad DX12, the RTX 4070 Ti scores 5024 against the RX Vega 64’s 1669, a delta of -66.8% for the AMD card. This is not a marginal victory; the RTX 4070 Ti delivers roughly three times the raw performance in this modern DirectX 12 workload.

The compute-oriented tests tell a similar story. In Geekbench OpenCL, the RTX 4070 Ti posts 176953 versus 62552 for the RX Vega 64, a -64.7% difference. The Vulkan result is even more lopsided: 213808 for NVIDIA against 67032 for AMD, a -68.6% delta. Across all three benchmarks, the RTX 4070 Ti’s smallest advantage is 64.7%, meaning the older AMD card never comes within striking distance.

Interestingly, the RX Vega 64’s average benchmark score of 50001 places it in the 86th percentile of all GPUs, while the RTX 4070 Ti’s average of 44795 sits in the 84th percentile. This apparent contradiction — where the slower card has a higher average — stems from the different benchmark suites each card was tested with. The RX Vega 64’s Geekbench Metal score of 68750 and Vulkan score of 67032 inflate its average, while the RTX 4070 Ti’s PassMark DX9 score of 352 and DX12 score of 116 drag its average down despite its clear superiority in the shared tests.

The nearest rivals for each card reinforce the generational gap. The RX Vega 64 sits within 0.1% of the RTX 5070 Ti (49957) and 0.5% of the Intel Arc A550M (49737), while trailing the RX 6900 XT by 1.9% and leading the RX 6800 XT by 3.1%. The RTX 4070 Ti, meanwhile, is 0.8% behind the RTX 5090 Mobile, 1.3% behind the AMD Radeon Pro 5500 XT, 1.6% ahead of the RTX A6000, and 1.7% behind the Intel Arc A730M. These clusters suggest the RX Vega 64 is competitive with mid-range 2024-2025 hardware, while the RTX 4070 Ti holds its own against top-tier mobile and professional parts.

Architecture Differences

The architectural chasm between these two cards explains the benchmark results. The RX Vega 64 uses GCN 5.0 architecture on a 14 nm process from GlobalFoundries, with a massive 495 mm² die housing 12,500 million transistors. The RTX 4070 Ti employs Ada Lovelace on TSMC’s 5 nm node, packing 35,800 million transistors into a smaller 294 mm² die. This translates to a transistor density of 121.8M per mm² for NVIDIA versus 25.3M per mm² for AMD — a 4.8x density advantage that enables more compute units in less space.

Core counts differ dramatically. The RX Vega 64 has 4096 shading units, 256 TMUs, and 64 ROPs, while the RTX 4070 Ti boasts 7680 shading units, 240 TMUs, and 80 ROPs. The RTX 4070 Ti also adds 60 RT cores and 240 tensor cores, hardware that the RX Vega 64 entirely lacks. This explains the RTX 4070 Ti’s FP32 throughput of 40.09 TFLOPS versus 12.66 TFLOPS for the RX Vega 64 — a 3.2x gap that mirrors the 3DMark result.

Clock speeds amplify the core count advantage. The RTX 4070 Ti boosts to 2610 MHz from a 2310 MHz base, while the RX Vega 64 boosts to 1546 MHz from 1247 MHz. Memory configurations also diverge: the RX Vega 64 uses 8 GB of HBM2 on a 2048-bit bus (483.8 GB/s bandwidth), while the RTX 4070 Ti uses 12 GB of GDDR6X on a 192-bit bus (504.2 GB/s). Despite the narrower bus, the RTX 4070 Ti achieves higher bandwidth thanks to faster memory clocks (21 Gbps effective versus 1890 Mbps effective).

API support reveals another generational split. The RTX 4070 Ti supports DirectX 12 Ultimate (12_2) and Vulkan 1.4, while the RX Vega 64 is limited to DirectX 12 (12_1) and Vulkan 1.3. Both cards support OpenGL 4.6. The RTX 4070 Ti also uses PCIe 4.0 x16 versus PCIe 3.0 x16 on the RX Vega 64, though this likely matters little for gaming performance.

FAQ

Q: Which card has higher raw compute performance?

A: The RTX 4070 Ti delivers 40.09 TFLOPS FP32 versus 12.66 TFLOPS for the RX Vega 64. The RTX 4070 Ti also offers FP16 at 40.09 TFLOPS (1:1), while the RX Vega 64 provides 25.33 TFLOPS FP16 via a 2:1 ratio.

Q: How do memory bandwidth and capacity compare?

A: The RX Vega 64 has 8 GB of HBM2 on a 2048-bit bus with 483.8 GB/s bandwidth. The RTX 4070 Ti has 12 GB of GDDR6X on a 192-bit bus with 504.2 GB/s bandwidth. The RTX 4070 Ti offers 25% more capacity and higher bandwidth despite a much narrower bus.

Q: What are the power requirements for each card?

A: The RX Vega 64 has a TDP of 295 W and requires a 600 W PSU with 2x 8-pin connectors. The RTX 4070 Ti has a TDP of 285 W, also suggests a 600 W PSU, but uses a single 16-pin connector.

Q: Which card supports hardware ray tracing?

A: Only the RTX 4070 Ti includes dedicated RT cores (60 of them). The RX Vega 64 has no RT cores, meaning ray tracing workloads will perform significantly worse on the AMD card.

Q: How does each card rank among all GPUs?

A: The RX Vega 64 sits in the 86th percentile with an average benchmark score of 50001, while the RTX 4070 Ti is in the 84th percentile with 44795. The RX Vega 64’s higher percentile reflects a different benchmark suite, not superior performance.

Q: Are there any benchmarks where the RX Vega 64 wins?

A: No. Across all three shared tests (3DMark Steel Nomad, Geekbench OpenCL, Geekbench Vulkan), the RTX 4070 Ti wins with deltas ranging from -64.7% to -68.6% in favor of NVIDIA.

The Verdict

The data is unequivocal: the RTX 4070 Ti is the superior performer in every measurable shared workload. Its 3.2x FP32 advantage, 3x 3DMark Steel Nomad score, and 2.8x Geekbench OpenCL result reflect a fundamental architectural leap rather than incremental improvement. The RTX 4070 Ti also offers 12 GB of memory versus 8 GB, higher bandwidth, and dedicated RT and tensor cores.

The RX Vega 64’s only statistical advantage is its higher percentile rank (86th versus 84th) and average benchmark score (50001 versus 44795), both artifacts of benchmark selection rather than real-world capability. Its nearest rivals include the RTX 5070 Ti (0.1% delta) and RX 6900 XT (-1.9%), placing it in the mid-range performance tier of modern GPUs.

For any workload — gaming, compute, or content creation — the RTX 4070 Ti is the clear choice. The RX Vega 64 remains relevant only for legacy system compatibility or as a historical reference point. The 14 nm GCN architecture cannot compete with 5 nm Ada Lovelace, regardless of the 495 mm² die size or 2048-bit memory bus.

AMD Radeon RX Vega 64:

• Higher percentile rank among all GPUs (86th vs 84th)
• Higher average benchmark score (50001 vs 44795)
• Wider memory bus (2048 bit vs 192 bit), though this does not translate to higher bandwidth
• Larger die area (495 mm² vs 294 mm²), offering more physical silicon per dollar historically
• Legacy PCIe 3.0 compatibility for older motherboards
• Dual 8-pin power connectors, which may be more compatible with older PSUs
